Posted By: Jake Hofer

If you’re a DIY home renovator looking to tackle your roofing project, understanding how to nail shingles correctly is crucial. The integrity of your roof relies significantly on the proper placement and securing of shingles.

Incorrect nailing can lead to:

In this detailed guide, we’ll walk you through everything you need to know about where to nail shingles, ensuring your roof is both durable and aesthetically pleasing.

Why Proper Shingle Nailing Is Important

Proper shingle nailing is essential for several reasons:

  • Weather Resistance: Correctly nailed shingles can withstand high winds and heavy rains, protecting your home from weather damage.
  • Longevity: Properly installed shingles last longer, offering better value for money and reducing the need for frequent repairs.
  • Aesthetic Appeal: Well-installed shingles lay flat and create a uniform appearance, enhancing your home’s curb appeal.
  • Warranty Compliance: Many shingle manufacturers require correct nailing for warranty validity. Incorrect nailing can void the warranty, leaving you financially vulnerable.

Understanding Shingles

Before we get into the specifics of where to nail shingles, it’s essential to understand the components of a shingle and the types of shingles commonly used in roofing.

Parts of a Shingle

A typical asphalt shingle consists of three main parts:

  • The Tabs: The exposed lower portion of the shingle.
  • The Sealant Strip: A strip of adhesive that helps bond shingles together once installed.
  • The Nailing Line: A guideline on the shingle indicating where nails should be placed.

Types of Shingles

There are different types of shingles, including:

3-Tab Shingles: Classic and cost-effective, featuring three tabs or cutouts along the lower edge.

Architectural Shingles: Thicker and more durable, offering a layered, dimensional look.

Wooden Shingles: Made from cedar or other types of wood, providing a natural aesthetic.

Tools and Materials Needed

Before you start nailing shingles, gather the following tools and materials:

  • Shingles
  • Roofing nails
  • Hammer or pneumatic nail gun
  • Measuring tape
  • Chalk line
  • Ladder
  • Safety gear (gloves, goggles, harness)

Preparing Your Roof

Ready to start your roof replacement? Prep your home for new asphalt shingles by doing the following

  • Inspection and Repair: Before installing new shingles, inspect your roof deck for damage. Replace any rotten or damaged wood to ensure a solid foundation for your shingles.
  • Underlayment Installation: Install roofing underlayment (felt paper or synthetic material) over the entire roof deck. This adds an extra layer of protection against moisture.
  • Drip Edge: Install a drip edge along the eaves and rakes of the roof. This metal strip directs water away from the fascia and into the gutters.

How to Nail Shingles: A 5-Step Guide

Install your roofing shingles the right way by following our expert guide to nailing shingles.

Step 1: Start with the Starter Strip

Begin by installing a starter strip along the lower edge of the roof. The starter strip provides a base for the first row of shingles and prevents water from seeping under the shingles.

  • Align the Starter Strip: Ensure the starter strip overhangs the roof edge by about ¼ to ¾ inch.
  • Nail the Starter Strip: Place nails about 3 to 4 inches from each end and evenly spaced across the length of the strip.

Step 2: Lay the First Row of Shingles

Once the starter strip is in place, you can start laying the first row of shingles.

  • Position the Shingles: Align the bottom edge of the first shingle flush with the starter strip, pressing it firmly against the sealant strip.
  • Nail the Shingles: Place nails on the nailing line of the shingle, typically about 5/8 to 3/4 inch above the cutouts for 3-tab shingles. Ensure that nails are driven straight and flush with the surface of the shingle but not so deep that they cut into the shingle.

Step 3: Continue Laying Shingles

Continue laying shingles row by row, following these guidelines:

  • Stagger the Shingles: Each row should start with a half shingle to create a staggered pattern, which helps prevent leaks.
  • Nail Placement: Ensure nails are placed about 1 inch from each end of the shingle and directly on the nailing line.
  • Overlap Shingles: Overlap the shingles correctly to cover the nails of the previous row, ensuring water flows over the shingles without penetrating beneath them.

Step 4: Work Around Roof Features

When you encounter roof features like vents, chimneys, and valleys, use the following tips:

  • Roof Valleys: For open valleys, install a metal valley liner and cut shingles to fit along the edges. For closed valleys, weave the shingles alternately from each side of the valley.
  • Roof Vents and Chimneys: Install flashing around vents and chimneys to prevent leaks. Cut shingles to fit snugly around these features and secure them with roofing cement and nails.

Step 5: Install Ridge Cap Shingles

Ridge cap shingles cover the peak of the roof, providing the finishing touch.

  • Cut the Ridge Cap Shingles: Cut regular shingles into individual ridge caps or purchase pre-made ridge cap shingles.
  • Position the Ridge Caps: Lay the ridge caps along the peak, overlapping each piece.
  • Nail the Ridge Caps: Place nails on each side of the ridge cap, about 1 inch from the edge. Ensure nails penetrate through both layers of the ridge cap and into the roof deck.

Common Mistakes to Avoid

As a new DIYer, it can be easy to install your roofing material incorrectly. Here are a few things to watch out for:

Overdriving or Underdriving Nails

  • Overdriving: Nails driven too deep can damage the shingle and reduce its holding power.
  • Underdriving: Nails not driven deep enough won’t hold the shingle securely in place. Ensure nails are flush with the surface of the shingle.

Incorrect Nail Placement

Ensure nails are placed on the nailing line for maximum holding power. Nails placed too high or low can compromise the shingle’s integrity.

Not Using Enough Nails

Using fewer nails to save time or materials can lead to shingle blow-offs in high winds. Follow the manufacturer’s guidelines for the correct number of nails per shingle.

Ignoring Manufacturer Guidelines

Always follow the shingle manufacturer’s installation guidelines, as they provide specific instructions for nailing and placement.
